yeah that was really off-putting. You're going to a dentist, not a speed dating event.

On space limited laptop keyboards yes, but you can get all of those with chording. Except the right hand control key of course.

Logitech in particular do this. Their keyboards adapt to the OS so the keys are in the right place, not sure if this needs their drivers or not though.

Withdrawal effects, like the beneficial effects, are highly individual. I had no withdrawal effects from escitalopram after being on it for a couple of years but I know people who’ve had the issues described in the article.

This isn’t a one size fits all area of medicine.

Likewise commercial aircraft have bypasses on the fuel and oil filters in case they get clogged in flight. The engine will need a thorough inspection if this happens but it's better to damage the engine if it gets you to the nearest airfield.

If you lose cooling the reactor will certainly trip but it will take several hours until you start to get core damage - 4 hours in the case of Fukushima Daiichi according to the released timeline. This also requires multiple redundant power supplies and cooling systems fail.

New Zealand locked down less than a lot of countries, but other than people with health problems I see no signs that people aren't going out any more due to Covid.

However due to other reasons people definitely have less money for discretionary activities, especially the youth.

And no, Covid never ended. It's still here, it's still killing and disabling people, but due to vaccines and antivirals it's less prevalent than it was.

GDPR Article 17 expressly requires the removal _of your personal data_ from the internet _upon your request_, which is very different from a US state trying to remove a website hosted in and run by a company incorporated in another country.

And geo blocking may be functionally impossible but the law cares about intent and actions, not if you prevented someone who used a VPN or lied about their location from using your service.

Really? Where I live a patient is always able to refuse any medical procedure or treatment, unless they’re unconscious or otherwise mentally unable and the procedure is considered necessary to save their life. They certainly can opt for a non-ambulance transfer, though here it would be free even though a regular ambulance service typically isn’t.

Consent for treatment is a core principle of medical practice.

I have a Polestar 2, 2022 model even so it's not fresh off the lot.

CarPlay navigation shows on the instrument cluster. The speed, state of charge, etc all move to the side so the map is right in the middle for quick viewing. Then the infotainment screen can show music or the tiled music/navigation view that CarPlay supports.

Basic music controls are on the steering wheel of course, readily accessible.

The lack of multitouch is slightly annoying, but it's not something I ever use. If I ever can't see what I need on the navigation I simply look outside for the road signs, which still exist.

A lack of wear components.

A permanent magnet motor uses permanent magnets on the rotor, but an electrically excited synchronous motor has an electromagnet on the rotor. This requires a rotating electrical contact which has normally been made with slip rings and carbon brushes. These wear over time and need replacement.

Most large electric generators are externally excited synchronous generators using carbon slip rings, so it's a well understood field.

This can be made contactless using inductive coupling and a rectifier - since inductive coupling needs AC but the excitation coil needs DC - at the expense of some efficiency.

You can see the efficiency difference - Renault claim 92% efficiency but permanent magnet motor EVs have touted efficiency over 95% in the motor.

Structural colour works by destructive interference of reflected light. It requires the light to be scattered for this effect, so light travelling through at 90° won't be affected.

On the image in the article you can still see a trace of the image on the active screen from indirect light.

Higher quality video https://www.youtube.com/watch?v=EdoLjsp5hkM, you can see the landing gear just after 8 seconds for one frame.

The notification contents are sent over secure channels but are not end-to-end encrypted.

You can add additional data to the payload and have a helper app decrypt on the device when a notification is received.

When it was developed it was assumed that the cost of cellular equipment and, in some countries, the regulatory hurdles required to get authorisation to purchase radio transmitters that operate on licensed bands would make it almost impossible to do this.

I worked in a company that had a base station emulator in their testing lab in 2008. I can’t recall the cost but it was well over $10,000 and only worked with direct antenna coupling, it couldn’t broadcast.

Now we have software defined radios.
